Brain cells that help raise blood sugar when it drops
GABA neurons in the ventromedial hypothalamus contribute to the counterregulatory response
['FUNDING_R01'] · LSU PENNINGTON BIOMEDICAL RESEARCH CTR · NIH-11323066
This project looks at a specific group of brain cells that sense low blood sugar and help trigger the body's response, which could matter for people who get dangerous hypoglycemia.

What this research studies
Researchers will focus on a small population of GABA-producing neurons in the ventrolateral part of the ventromedial hypothalamus that appear to change activity when glucose falls. In animal models they will watch these cells' activity with fiber photometry and electrophysiology, control them with optogenetics, profile their genes using Patch-seq, and alter genes with CRISPR. The team will measure how turning these cells on or off affects hormone release and blood glucose recovery after low blood sugar. The goal is to reveal mechanisms that could point to new ways to prevent or treat severe hypoglycemia.
Who could benefit from this research
Good fit: People with type 1 diabetes or insulin-treated type 2 diabetes who experience recurrent or severe hypoglycemia would be the most likely candidates for future studies based on this research.
Not a fit: People without blood sugar problems or whose symptoms are not caused by hypoglycemia are unlikely to benefit from this work.
Why it matters
Potential benefit: If successful, this work could point to new approaches to prevent or treat dangerous low blood sugar in people with diabetes.
How similar studies have performed: Other studies have shown hypothalamic neurons help trigger counterregulation, but targeting this specific GABAergic neuron population is a newer and less-tested approach.
